America's founders specifically designed a three-branch system of government that precludes any single person from ruling the country. The three branches of American government are the executive branch, legislative branch, and judicial branch.
The Constitution of the United States describes the duties of each branch of government:
- Under Article II of the Constitution, the executive branch, or president, enforces laws passed by Congress, appoints a 15-person cabinet, and commands the armed forces.
- Under Article I of the Constitution, the legislative branch, or Congress, passes laws, declares war, tries impeachments, and approves or rejects presidential appointments.
- Under Article II of the Constitution, the judicial branch has the power to determine the constitutionality of laws passed by Congress.
This system of checks and balances ensures branches are interdependent and unable to rule alone.
